The only standard we have for judging all of our social, economic, and political institutions and arrangements as just or unjust, as good or bad, as better or worse, derives from our conception of the good life for man on earth, and from our conviction that, given certain external conditions, it is possible for men to make good lives for themselves by their own efforts.

In Aristotelian terms, the good leader must have ethos, pathos and logos. The ethos is his moral character, the source of his ability to persuade. The pathos is his ability to touch feelings to move people emotionally. The logos is his ability to give solid reasons for an action, to move people intellectually.
